Oven temperatures and Conversions

Oven temperatures

All Delia's recipes are tested thoroughly using conventional ovens.

For fan assisted ovens, if you are not able to switch off the fan function, we suggest you reduce the temperature by 20 degrees or check the manufacturer's handbook, although cannot guarantee the results in the same way we can for conventional ovens.

We also strongly recommend you use an oven thermometer at all times.

Conversions

All these are approximate conversions, which have either been rounded up or down. In a few recipes, it has been necessary to modify them very slightly. Never mix metric and imperial measures in one recipe; stick to one system or the other.

All spoon measurements on this site are level, unless specified otherwise.

All butter is salted, unless specified otherwise.

In Delia's recipes she uses large eggs, unless otherwise stated

All recipes are tested using whole milk, unless specified otherwise.
